1) Did you use the Gel Method?
If you answered yes - most gel formulas, ours included, contain UV blockers that prevent the glows from charging. The UV blockers help prevent yellowing, which is great but it lessens the glow.
2) If you didn’t use the gel method, take some time to let your glow powders soak up some UV light. They’ve been in a dark shipping package for a bit and it’s not that sunny in our warehouse so they can use a bit of charging! Pop those babies out in the sun for a few minutes and they’ll be ready to GLOW!
